The center of the model domain is computed using GEMPAK's Gaussian Weighted Filter using normal distribution of weights (GWFS) for the 24 hour precipitation field (P24M) accumulated from F006 to F030. The weighted field is interpolated to CONUS station locations using GEMPAK's GDGSFC program. The model central latitude and longitude is obtained from the station location with the maximum weighted ROI value. This field is shown in the lower left panel of the Regional Model Run index pages. The central latitude/longitude for the model run is shown at the bottom of each page.
A floater radar composite image product for the inner nest of the model domain is generated from available 1km NIDS imagery at 5 minute intervals for the 30 hour time period of interest. This product is shown in the upper right panel of the Regional Model Run index pages, and selected frames may be animated by clicking on the image.
The Regional Model run uses 3 hour NAM grids from F000-F030 for the forecast domain Model output for the 5km forecast grid is generated hourly through 30 hours from the initial boundary run time. A display of selected forecast fields is shown in the lower right panel of the Regional Model Run index pages. Selected frames may be viewed/animated by clicking on the image.
Products for each model run are being inserted into the LDM for distribution. The naming convention for these products is evolving. The current set of products includes:
